  1. 1. Biomarkers for assessing benthic pollution impacts in a subtropical estuary, Mozambique

    Författare :Maria Perpétua Janeiro Scarlet; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; subtrophical estuary; contaminants; biological hierarcial biomarkers; scope for growth; burrowing response; acethylcholinesterase; benthic fauna; southern Mozambique;

    Sammanfattning : This thesis focuses on the marine environment in a subtropical estuary and particularly on exploring a suite of easy-to-use, cost effective and environmentally valid biological response tools (biomarkers). The main driving force of the thesis is the knowledge of the numerous anthropogenic impacts. LÄS MER

  3. 2. Transport by Benthic Macrofauna: Functional Classification and Biogeochemical Response

    Författare :Stina Lindqvist; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine sediments; Early diagenesis; Bioturbation; Functional groups; Benthic fluxes; Imaging; Ecosystem function; Sediment reworking; Transport proxies; Fluorescent particles;

    Sammanfattning : Burrowing and reworking activities by benthic macrofauna regulate rates and pathways during organic matter mineralisation in bioturbated sediments. In so doing, they also affect the overall cycling of elements crucial in the biosphere (e.g. C, N, P, Fe, Mn and S). LÄS MER

  4. 3. Allergy and Alzheimer disease

    Författare :Heela Sarlus; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer disease (AD) is a neurodegenerative disorder characterized by progressive dementia with devastating effects for the patients and their families. The treatments available are purely symptomatic and there is need for treatment strategies aiming at the etiopathogenesis of AD. LÄS MER

  5. 4. The role of sediments in the biogeochemical cycles of nutrients in the Gulf of Riga

    Författare :Juris Aigars; Matti Perttilä; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; biogeokemi;

    Sammanfattning : The sediment biogeochemistry of C, N, P and biologic silica (BSi) plays an important role in cycling of these elements in aquatic ecosystems. In shallow coastal and estuarine systems, water-sediment nutrient dynamics can influence biological processes (e.g., primary production) in overlying waters. LÄS MER
